Graph-theoretic approach to dimension witnessing
New Journal of Physics, 2021 A fundamental problem in quantum computation and quantum information is finding the minimum quantum dimension needed for a task. For tasks involving state preparation and measurements, this problem can be addressed using only the input–output ...

Small values of the Lusternik-Schnirelmann category for manifolds [PDF]
, 2007 We prove that manifolds of Lusternik-Schnirelmann category 2 necessarily have free fundamental group. We thus settle a 1992 conjecture of Gomez-Larranaga and Gonzalez-Acuna, by generalizing their result in dimension 3, to all higher dimensions.

On The Potential of Minimal Flavour Violation [PDF]
, 2011 Assuming the Minimal Flavour Violation hypothesis, we derive the general scalar potential for fields whose background values are the Yukawa couplings. We analyze the minimum of the potential and discuss the fine-tuning required to dynamically generate ...

Mass anomalous dimension in SU(2) with six fundamental fermions [PDF]
, 2010 We simulate SU(2) gauge theory with six massless fundamental Dirac fermions. We measure the running of the coupling and the mass in the Schroedinger Functional scheme. We observe very slow running of the coupling constant.

Nueva agricultura y multifuncionalidad:
Revista de Fomento Social, 2003 El mundo rural se enfrenta en la actualidad a nuevos desafíos. Desbordando un enfoque estrictamente productivista, que atribuía al campo la única función de producir alimentos, se está desembocando en el descubrimiento de nuevas dimensiones.

Light-cone formulation of conformal field theory adapted to AdS/CFT correspondence [PDF]
, 2006 Light-cone formulation of conformal field theory in space-time of arbitrary dimension is developed. Conformal fundamental and shadow fields with arbitrary conformal dimension and arbitrary spin are studied.

Fischer decomposition for massless fields of spin 1 in dimension 4 [PDF]
, 2017 The massless field equations for lower integer and half-integer values of spin in Minkowski space are fundamental equations in mathematical physics. Their counterpart in Euclidean spacetime is a system of elliptic equations, which was already studied ...

Fundamental Dimension and Suspension of Approximate Fibrations [PDF]
Proceedings of the American Mathematical Society, 1980 Given an approximate fibration f : X → Y f:X \to Y between ANR’s a new approximate fibration Sf is constructed with the property that the fibers of Sf are the suspensions of the fibers of f. This construction is used together with an approximation theorem of T. Chapman to give conditions under which

Counting Process Based Dimension Reduction Methods for Censored Outcomes [PDF]
, 2018 We propose a class of dimension reduction methods for right censored survival data using a counting process representation of the failure process. Semiparametric estimating equations are constructed to estimate the dimension reduction subspace for the ...
